Specification of Letters Patent. Pgt t d'J 1 5 Application filed July 8,1913. Serial No; 777,834.

Be it known that I, PONTUS OSTENBERG, av citizen of the United States,residingat'Los Gatos, in the county of Santa Clara and State ofCalifornia, have invented a new and useful Internal-Combustion Turbine-Engine, of which the following is a specifi cation.

My invention relates to internal combustion turbine engines.

One object of 'myinvention is to provide v an engine in which thedriving power is pro one w i h may be adapted to any purpose where weris required.

' In the accompanying drawings, Figure 1 is a side elevation of myinternal combustion turbine engine. Fig. 2 is a front elevation of thesame. Fig. 3 is a vertical section on line A-A of Fig. 2.-- Fig. 4 is avertical 1 section on line BB of Fig. 2. Fig. 5 is a vertical section online C-G of Fig.1. Fig.-

6 is a horizontal section on line DD of Fig. 2. Similar referencenumerals designate corresponding parts in all the figures of thedrawings.

R ferring more particularly to the drawings, my invention is describedas follows The numerals land 2 represent the body portions of myinvention, the samebeing .cast in two separate parts, and may be made ofcast iron or any other suitable material and bolted together by boltsshown at 3. The upper parts of said body-portions 1 and 2 arecylindrical in form, of the proper length and proper diameter and areapproximately Vertical in position. In the proper position near theupper ends of said cylindrical portions are ofl'sets cast therein shownat 4C. In

the top of said offsets 4 are placed a plurality of exhaust valves shownat 5. At the extreme top of said cylindrical portions 1 and 2 are shownintake valves 6, Which are for the purpose of admitting the explosivevapor taken in from any ordinary carbu reter. Said explosive vapor maybe exploded by means of a'hot ball as shown atl', or any other suitablemeans. Try-cocks are show'n at 8, which'are for the purpose ofdesignating the height of water in said cylindrical portions. l/Vaterinlet'valves are shown at 9 "which are for the purpose of admittingWater to said'cylindrical portions, -1 and 2. The body portions 1 and 2are cast in separateparts, the base-being in the form of a scroll asshown' at 10, Figs. 1 andf3, leaving a hollow space therein into whichis placed a turbine wheel 11 said wheel being keyed. to-shaft 12, saidshaft 12 resting in bearings 13. Inside of said base and 'in eachsection thereof are cast partitions. '14 "having-ports 1 5 slantinginwardly. through saidpartions as shown in Figs. 3, 5, and 6,

force of the water against the vanes 16 on turbine wheel 1.1, in eitherdirec tion driving said turbine wheel ll'always in the same direction,said vanes 16 being supported by an outer rim 16. At the v and are forthe purpose of directing the lower parts of said cylindrical portions-1- and 2 is cast a port Said port is opened and closed by a valveshownat 18 and is for thepurpose of governing the speed of said turbine wheel11. Said valve 18 is operated by any suitable connection attached tovalve-' stem 19.

The operation of my engine is as follows :-The cylinders are filled with,water through inlet valve 9 to the level of trycock 8. Amharge of gasis. admitted to the upper portion of each cylinder through any ordinarycarbureter. The charge of gas in one cylinder is then exploded, saidexplosion forcibly driving the water downward in that cylinder andthrough all of the ports on that side of the turbine wheel, against thevanes of the turbine wheel and up through the ports in the scroll of thesecond cylinder. The body of water ascendingin the second cylindercompresses the gas in said second cylinder which, when exploded, drivesthe body of waterback through its ports against the vanes of the turbinewheel and back through the ports in the first cylinder. The

parts of this engine are so proportioned that When the water is drivenfrom one cylinder by the gas explosion it causes a vacuum and afreshcharge of gas is drawn in through inlet valve 6 to fill that portion ofthe cylin- 'der above the exhaust valves. When the water returns to thecylinder after each explosion it drives the exhaust out of said cylinderthrough the exhaust valves 5 until the water itself reaches and closessaid valves 5 when the charge of gas in that portion of the. cylinderabove the exhaust valves is compressed and exploded and the operation isalternately repeated. The gas and air mixture will not explode untilthesame has been compressed, and this compression does not occur untilafter the expanded gases have been discharged through valves 5 and theonrushing water has closed valves 5, continuing on upward tocompression. Valves .5 are so balanced that they will lift just enoughto allow the expanded gases to escape therethrough, andclose instantlywhen the water reaches them. lVhen the compressed gases are exploded byhot ball? the exhaust valves 5 are closed on their lower seats. As thewater descends with force by said explosion it forms a vacuum whichcauses said valves 5 to take their upper seats, and by this same .vacuuma fresh charge of gas'and air mixture is drawn into the upper part ofthe cylinder above the exhaust valves 5 "through valve 6, operatingalternately. It

is shown by experience that the expanding gases operating as abovestated do not mix with the fresh charge drawn in to the upper 'part ofsaid cylinders to any extent, as the exhaust valves 5 operate quicklyand discharge the expanded gases without any loss of water throughsaidexhaust valves 5. To

reduce the speed of the turbine wheel the valve 18 is opened a distanceand the supply of gas reduced thus driving a portion of the waterthroughthe passage '17 with .reduccd force and diminishing'both the quantityand force of the water driven against the turbine, but not changing thecompression in the upper part of the cylinder.

Having thus fully described my invention what I claim as new, and desireto secure by Letters Patent, is
